In this paper, a new concentric Hamming linear aperture is suggested. The point spread function (PSF) is computed for concentric Hamming linear aperture and it is compared with the corresponding circular, conventional Hamming and obstructed Hamming apertures. In addition, the autocorrelation corresponding to the aperture under consideration is computed and plotted. Application of the Hamming linear aperture in the formation of modulated speckle images of Ramses II statues using definite random diffuser is given. A diffuser limited by a circular uniform aperture is the basic element in the formation of ordinary speckle images located in the Fourier plane. Meanwhile, the Fourier spectrum of images of Ramses II multiplied by the ordinary speckle give modulated speckle images. Discrimination between the modulated speckle images is justified by comparing the profiles corresponding to each speckle image. Finally, the speckle contours and correlation of the modulated speckle images compared to the ordinary speckle images are investigated. It is noted that all computation and formation of images and plots are based on fast Fourier transform (FFT) techniques using Matlab codes.

拉美西斯二世雕像的图像处理使用由新汉明线性孔径调制的散斑摄影

在本文中，提出了一种新的同心汉明线性孔径。计算同心汉明线性孔径的点扩散函数 (PSF)，并将其与相应的圆形、传统汉明和受阻汉明孔径进行比较。此外，计算并绘制与所考虑的孔径对应的自相关。给出了汉明线性孔径在使用确定随机漫射器形成拉美西斯二世雕像调制散斑图像中的应用。受圆形均匀孔径限制的漫射器是形成位于傅立叶平面内的普通散斑图像的基本元素。同时，Ramses II 图像的傅里叶谱乘以普通散斑得到调制散斑图像。通过比较对应于每个散斑图像的轮廓来证明调制散斑图像之间的区别是合理的。最后，研究了调制散斑图像与普通散斑图像相比的散斑轮廓和相关性。需要注意的是，图像和绘图的所有计算和形成都是基于使用 Matlab 代码的快速傅立叶变换 (FFT) 技术。
